This morning I claimed to have suffered from Braxton Hicks for the first time in my blog this morning and now it's 3:57pm and it has come back. I wonder if this is all real labor and that I'm just at the very beginning stages? I am already 39 weeks today so it is possible right?

As I was walking around the house, I did feel like my right leg would get weak all of a sudden like a sudden shot through my leg went up my spine and I had to stop for a second a few times. Is this caused by my contractions?

I've been told that contractions during labor are very painful and you would barely be able to walk. I wonder if my pain tolerance is really high and that those very intense contractions could only be felt by some?
